Lithium is considered first choice in the prevention of prospective episodes in patients with bipolar disorder. However, efficacy is not satisfactory in all patients and side effects sometimes prevent the use of lithium. It is argued that efficacy in clinical practice may be less impressive than anticipated from clinical trials, and alternative treatments are beinu advocated increasingly for that reason, such as the anticonvulsants, carbamazepine and valproate.
